摘要
随着锂离子电池在生活和工作中的普及,锂离子电池的安全事故逐年增加,锂离子电池的安全研究逐渐引起学术界的关注。研究锂离子电池的热安全性,可以有效分析锂离子电池发生起火和爆炸的内在原因,指导锂离子电池安全性研究的开展。本文介绍了锂离子电池工作过程中产热的来源和影响因素,以及锂离子电池热失控发生时的内部反应和反应对应的温度,并对电池热失控时的热特性参数进行了总结。
With the popularity of lithium-ion batteries in life and work, the safety accidents of lithium-ion batteries have increased year by year, and the safety research of lithium-ion batteries has gradually attracted the attention of the academic community. Studying the thermal safety of lithium-ion batteries can effectively analyze the internal causes of ignition and explosion of lithium-ion batteries and guide the research on the safety of lithium-ion batteries. This paper describes the sources and influencing factors of heat production during the operation of lithium-ion batteries, as well as the internal reaction and temperature corresponding to the thermal runaway of lithium-ion batteries, and summarizes the thermal characteristics of the battery when it is out of control.
